------------------------------------
Summary: Getting OutOfMemoryError after Jenkins has been running
for several days
Key: JENKINS-13827
URL: https://issues.jenkins-ci.org/browse/JENKINS-13827
Project: Jenkins
Issue Type: Bug
Components: core
Environment: Jenkins 1.458
Red Hat Enterprise Linux ES release 4 (Nahant Update 4)
32-bit hardware and OS
java 1.6.0_17
perforce plugin 1.3.8
8 virtual CPUs
16 GB total available memory on the system
Reporter: Ed Palazzo
After running from anywhere from one to two weeks, Jenkins will appear to be
frozen. Examination of the logs shows the following error:
java.lang.OutOfMemoryError: GC overhead limit exceeded
I've done numerous stack dumps, and it is fairly inconsistent as to what is
happening when the error occurs. This last time I did a heap dump per the
instructions on this page:
https://wiki.jenkins-ci.org/display/JENKINS/I%27m+getting+OutOfMemoryError
The heap is available for download via FTP here:
ftp://Jenkins:[email protected]/heap.bin.gz
It's about 300M compressed (~1.6GB uncompressed). I had a hard time running
jhat against the heap -- maybe you'll have more luck.
I should let you know that I have 565 jobs (all modules of different branches)
configured on this system. I have one slave running builds, with another two
machines on the way.
Let me know what else I can provide to help debug.
